If you burn 48.6 g of hydrogen and produce 434 g of water, how much oxygen reacted?
GarryVolchara [31]

Answer:

            385.69 g of O₂

Solution:

The Balance Chemical equation for said reaction is as follow;

                                       2 H₂  +  O₂    →   2 H₂O

According to Equation,

        4.032 g ( 2 mol) H₂ reacts to produce  =  36.03 g (2 mol) of H₂O

So,

        48.6 g H₂ on reaction will produce  =  X g of H₂O

Solving for X,

                     X =  (48.6 g × 36.03 g) ÷ 4.032 g

                     X  =  434.29 g of H₂O

It means that the H₂ provided is in Excess. Therefore, the yield of product (H₂O) is being controlled by O₂ (Limiting Reagent).

So, According to Equation,

                    36.03 g (2 mol) H₂O is produced by  =  31.998 g (1 mol) of O₂

So,

                434.29 g of H₂O will be produced by  =  X g of O₂

Solving for X,

                     X =  (434.29 g × 31.998 g) ÷ 36.03 g

                    X  =  385.69 g of O₂

A 2. 00 g sample of cocl2. x h2o is dried in an oven. when the anhydrous salt is removed from the oven, its mass is 1. 565 g. wh
timofeeve [1]

It is Cobalt(II)chloride dihydrate. The value of x is 2.

First, we have to determine the mass of H₂O that was evaporated upon heating which will be = 2.00g - 1.56 g

                                 = 0.435 g

So,

CoCl₂ + x.H₂O → CoCl₂.xH₂O

Molecular mass of CoCl₂ = 129.839 g/mol

Molecular mass of H₂O = 18 g/mol

Weight of sample after heating = 1.565 g

Weight of H₂O evaporated = 0.435 g

Hence,

           18x = \frac{129.839X0.435}{1.565} \\x = \frac{55.48}{28.17} \\x = 1.9

           x ≈ 2

So, it is Cobalt(II)chloride dihydrate.

Caroline has a condition where the amount of oxygen her blood can hold is greatly reduced. This leads to a decrease in oxygen su
Sphinxa [80]
The correct answer is : Circulatory and respiratory.

This condition primarily affects Caroline's circulatory system. Since the main purpose of the circulatory system is to supply the rest of the body with oxygen, this condition is greatly reducing the effectiveness of the circulatory system.
The decrease in oxygen supply to the lungs causes the reduction of the respiratory system effectivness as well, since the lung cells need oxygen for their metabolic processes.
